What is The amperage rating of 350 MCM copper wire?

It depends on a lot of factors. Generally speaking, if the insulation is THHN then the rating is 350 amps. If the insulation is THWN then the rating is 310 amps. The ampere rating for wire depends on the temperature of the environment it will be used in, the insulation rating and the number of circuits installed in a conduit. There are also other factors to consider... like voltage drop in long runs.
